图1是根据本发明一示例性实施例示出的一种应用于电视的音频调试方法的工作流程示意图；
图2是根据本发明一示例性实施例示出的一种应用于电视的音频调试装置的结构示意图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。 相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本申请公开一种应用于电视的音频调试方法及装置，以解决现有技术中电视通过自身的音频采样率获取并播放该媒体源的音频时，有时音频会出现杂质的问题。
本申请的实施例一公开一种应用于电视的音频调试方法。参见图1所示的工作流程示意图，所述应用于电视的音频调试方法包括以下步骤：
步骤S11、当需要接收外接的媒体源中的音频时，获取所述音频的音频采样率。
本申请中，支持多种形式的外接的媒体源，例如，所述外接的媒体源可以为DVD刻录机、CD刻录机、U盘等移动存储设备和机顶盒等，本申请对此不做限定。
步骤S12、根据所述音频的音频采样率对所述音频进行采样，并将采样结果存储至存储区域。
电视具有自身固定的音频采样率，但外接的媒体源提供的音频可能存在多种的音频采样率。这种情况下，在本申请中，电视在获取音频本身的音频采样率后，通过音频的音频采样率进行采样。
步骤S13、当需要播放所述音频时，从所述存储区域中获取所述采样结果并播放。
本申请的第一实施例公开一种应用于电视的音频调试方法，该方法中，当需要接收外接的媒体源中的音频时，通过该音频的音频采样率对所述音频进行采样，并存储获取到的采样结果，当需要播放所述音频时，再从所述存储区域中获取所述采样结果并播放。通过该方法，电视通过音频本身的音频采样率接收并播放所述音频，从而避免音频出现杂质，提高了音频的质量。
例如，若电视的音频采样率被设置为48KHz，而外接的媒体源中的音频的音频采样率为44.1KHz，则电视以44.1KHz的音频采样率接收并播放该音频，避免音频出现杂质，保障了音频的质量。
另外，在本申请公开的方案中，所述获取所述音频的音频采样率，包括以下步骤：
首先，接收所述外接的媒体源传输的音频描述信息；
然后，对所述音频描述信息进行分析，获取所述音频描述信息中包含的所述音频的音频采样率。
其中，所述音频描述信息通常与音频封装成一个数据包。并且，在所述音频描述信息中，包含该音频的音频采样率。因此，通过对音频描述信息进行分析，即可获取所述音频的音频采样率。
进一步的，在本申请公开的应用于电视的音频调试方法中，公开了将采样结果存储至存储区域的操作。其中，所述将采样结果存储至存储区域，包括以下步骤：
首先，在通过所述音频描述信息获取所述音频的音频采样率后，判断所述音频的音频采样率与电视的音频采样率是否相同；
然后，若所述音频的音频采样率与电视的音频采样率相同，将所述采样结果存储至电视原有的存储区域中；若所述音频的音频采样率与电视的音频采样率不同，创建新的存储区域，并将所述采样结果存储至所述新的存储区域。
现有技术中，电视根据自身的音频采样率接收外接的媒体源提供的音频，并将接收到的音频存储至电视原有的存储区域中。这种情况下，在本申请中，若音频的音频采样率与电视的音频采样率相同，则将采样结果存储至所述电视原有的存储区域中。
另外，若所述音频的音频采样率与电视的音频采样率不同，则电视通常创建新的存储区域，并将采样结果存储至所述新的存储区域中，从而在播放音频时，便于实现对音频的查找。
进一步的，本申请公开的应用于电视的音频调试方法还包括：在存储所述采样结果时，建立存储所述采样结果的存储区域与采样结果之间的对应关系。
其中，若采样结果被存储至电视原有的存储区域中，则建立所述采样结果与所述电视原有的存储区域的对应关系，若采样结果被存储至新的存储区域，则建立所述采样结果与所述新的存储区域的对应关系。
在建立采样结果的存储区域与采样结果之间的对应关系后，当需要播放所述音频时，根据所述对应关系，即可查找到相应的存储区域，并获取所述存储区域中存储的采样结果并播放。
进一步的，本申请公开的应用于电视的音频调试方法还包括：
获取所述音频的属性信息，并存储所述音频的属性信息与所述音频的音频采样率的对应关系；当再次需要接收所述音频时，根据所述音频的属性信息以及所述对应关系，获取所述音频的音频采样率。
上述步骤中，在获取音频的音频采样率后，会存储音频的属性信息与所述音频的音频采样率的对应关系。这种情况下，当再次需要接收所述音频时，获取到所述音频的属性信息，继而可根据所述音频的属性信息以及所述对应关系，获取所述音频的音频采样率，从而不再需要对音频的描述信息进行分析。
相应的，本申请的第二实施例公开一种应用于电视的音频调试装置，参见图2所示的结构示意图，所述应用于电视的音频调试装置包括：获取模块100、采样存储模块200和播放模块300。
其中，所述获取模块100，用于当需要接收外接的媒体源中的音频时，获取所述音频的音频采样率；
所述采样存储模块200，用于根据所述音频的音频采样率对所述音频进行采样，并将采样结果存储至存储区域；
所述播放模块300，用于当需要播放所述音频时，从所述存储区域中获取所述采样结果并播放。
电视具有自身固定的音频采样率，但外接的媒体源提供的音频可能存在多种的音频采样率。这种情况下，在本申请中，电视在获取音频本身的音频采样率后，通过音频的音频采样率进行采样。
本申请的第二实施例公开一种应用于电视的音频调试装置，通过该装置，当需要接收外接的媒体源中的音频时，通过该音频的音频采样率对所述音频进行采样，并存储获取到的采样结果，当需要播放所述音频时，再从所述存储区域中获取所述采样结果并播放。通过该方法，电视通过音频本身的音频采样率接收并播放所述音频，从而避免音频出现杂质，提高了音频的质量。
例如，若电视的音频采样率被设置为48KHz，而外接的媒体源中的音频的音频采样率为44.1KHz，则电视以44.1KHz的音频采样率接收并播放该音频，避免音频出现杂质，保障了音频的质量。
进一步的，所述获取模块100包括：
描述信息接收单元，用于接收所述外接的媒体源传输的音频描述信息；
采样率获取单元，用于对所述音频描述信息进行分析，获取所述音频描述信息中包含的所述音频的音频采样率。
其中，所述音频描述信息通常与音频封装成一个数据包。并且，在所述音频描述信息中，包含该音频的音频采样率。因此，通过对音频描述信息进行分析，即可获取所述音频的音频采样率。
进一步的，所述采样存储模块200包括：
判断单元，用于在通过所述音频描述信息获取所述音频的音频采样率后，判断所述音频的音频采样率与电视的音频采样率是否相同；
第一存储单元，用于若所述音频的音频采样率与电视的音频采样率相同，将所述采样结果存储至电视原有的存储区域中；
第二存储单元，用于若所述音频的音频采样率与电视的音频采样率不同，创建新的存储区域，并将所述采样结果存储至所述新的存储区域。
现有技术中，电视根据自身的音频采样率接收外接的媒体源提供的音频，并将接收到的音频存储至电视原有的存储区域中。这种情况下，在本申请中，若音频的音频采样率与电视的音频采样率相同，则将采样结果存储至所述电视原有的存储区域中。
另外，若所述音频的音频采样率与电视的音频采样率不同，则电视通常创建新的存储区域，并将采样结果存储至所述新的存储区域中，从而在播放音频时，便于实现对音频的查找。
进一步的，本申请公开的应用于电视的音频调试装置还包括：
第一对应关系建立模块，用于在存储所述采样结果时，建立存储所述采样结果的存储区域与采样结果之间的对应关系。
在建立采样结果的存储区域与采样结果之间的对应关系后，当需要播放所述音频时，根据所述对应关系，即可查找到相应的存储区域，并获取所述存储区域中存储的采样结果并播放。
进一步的，本申请公开的应用于电视的音频调试装置还包括：
属性信息获取模块，用于获取所述音频的属性信息；
第二对应关系建立模块，用于存储所述音频的属性信息与所述音频的音频采样率的对应关系；
音频采样率获取模块，用于当再次需要接收所述音频时，根据所述音频的属性信息以及所述对应关系，获取所述音频的音频采样率。
通过本申请公开的属性信息获取模块、第二对应关系建立模块和音频采样率获取模块，在获取音频的音频采样率后，会存储音频的属性信息与所述音频的音频采样率的对应关系。这种情况下，当再次需要接收所述音频时，获取到所述音频的属性信息，继而可根据所述音频的属性信息以及所述对应关系，获取所述音频的音频采样率，从而不再需要对音频的描述信息进行分析。
关于上述实施例中的装置，其中各个模块执行操作的具体方式已经在有关该方法的实施例中进行了详细描述，此处将不做详细阐述说明。
在本发明的第三实施例，还提供一种终端，所述终端包括第二实施例提供的应用于电视的音频调试装置。
本发明实施例还提供一种计算机存储介质，其中，该计算机存储介质可存储有程序，该程序执行时可实现图1所示实施例提供的一种应用于电视的音频调试方法的各实现方式中的部分或全部步骤。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
